How to simplify 5(x-8)+10

Answers

Answer:

5x - 30

Step-by-step explanation:

5 must multiply with what's in the bracket for being next to it

5 x X = 5x

5 x -8= -40

5x - 40 + 10

- 40 + 10 = -30

5x - 30

Answer:

-30+5x

Step-by-step explanation:

5(x-8)+10

x-8 evaluates to x-8

Multiply 5 by x-8

we multiply 5 by each term in x-8 term by term.

This is the distributive property of multiplication.

Multiply 5 and x

Multiply 1 and x

The x just gets copied along.

x

5 × x = 5x

Multiply 5 and -8

1

5 × -8 = -40

5*(x-8) evaluates to 5x-40

-40 + 10 = -30

The answer is -30+5x

5*(x-8)+10 evaluates to -30+5x

every 1/2 hour Naomi stretches her neck; every 1/3 hour she stretches her legs; and every 1/6 hour she stretches her arms. Which parts of her body will Naomi stretch when 2/3 of an hour has passed?

Answers

Naomi will stretch each part if her body listed because 1/2 is less than 2/3. She will have stretched her neck once;1/3 is less than 2/3. 1/3 + 1/3 is 2/3 so she would have stretched her arms twice;1/6 is less than 2/3 and goes into 2/3 4 times so she would have stretched her legs 4 times.Hope I helped!

Write and equation of a line that is parallel to the line below and passes through the given point

Answers

a line parrelel would have the same slope

in y=mx+b   m=slope and b=yintercept

so y=-2/3x-5 
the point you want is -3,11 or this equation is true when x=-3 and y=11 are true so subsitute and solve for the new 'b'

11=-2/3(-3)+b
11=2+b
subtract 2 from both sides
9=b

the equaqtion is y=-2/3x+9
If one line is parallel to another, that means the two lines have the same slope.  Therefore, since the line you are creating is parallel to the line y = -2/3x - 5, it's slope must be the same, -2/3.  Additionally, you know it passes through the point (-3, 11).

If you don't remember the slope-intercept equation, it looks like this:
y = mx + b, where m is the slope, b is the y-intercept, and x and y are, well, x and y.

Let's plug in the slope we know it must have (-2/3)  and plug in the (x, y) coordinates we were provided so that we can find b.
11 = -2/3(-3) + b

Solve for b:
11 = 2 + b
9 = b

Now we know our slope and our y-intercept, after solving for it, so we can write our final equation!

The answer is: y = -2/3x + 9

Find the value of the expression.

5200 – [40%(300 * 42.5)]

Answers

Answer:

The value of the expression is 100

Step-by-step explanation:

we have

5,200-[40%(300*42.5)]

we know that

(300*42.5)=3*100*42.5=3*4,250=12,750

40%=40/100=0.40

substitute

5,200-[0.40*12,750]

5,200-5,100=100
